Hey Guy/rs i just got a ryzen 3600 x for my asrock b450m-hdv r4.0 (i now! am still using 2600:) When installed 3600x first time it did not work. after that it kind a did ;) a couple of times...(long loading times...) Now: it randomly posts or does not at all. asrock site says mobo is 3 gen. ready!
But in my case it is not!
Believe me i tried everything to get it work out...
Bios from old to new, single ram, and all that!
Why is this happening?
here is my system:
B450M-HDV r4.0
RTX 2070 super (msi ventus oc)

Hi guys,

I am a little stuck here if you can help would be great.
I ordered the parts I saw on a Dutch website without doublechecking, and it seems like the configuration is not really that awesome for a first time builder.
The mobo I read is really good price performance but it does not even have a pc beep so I dont even know whats wrong.

- Apparently this mobo does not support G.Skill Aegis F4 3000.
-not even sure on the bios version of the mobo I have.

I am going to return the memory but I dont even know what would work on this mobo any more. Many thanks for your advise.
